CHARLES HUDSON, OF PHILADELPHIA, PENNSYLVANIA.

ICE-CREAM FREEZER.

Application filed Juneau, 1926. Serial in. 119,679.

My invention relates to ice cream freezers; and more particularly to a device tor freezing and whipping the cream it being so constructed that it may be used for freezing the ice cream in bulk or loose form and provided with a plurality of cans and dashers ditlering in size so that a variety of flavors can be whipped and frozen, and the contents removed from the cans and stored in suitable receptacles. It fancy or Neapolitan brick cream is desired the batches are whipped and frozen in the cans and a smooth velvet-like consistency is obtaincd, and the cans are then raised and the bobinet open top and dashers are removed from the cans; and a closed topmade for the purpose takes the place of the open top.

The object of the invention is to so; construct. the same that it will be simple, durable, easily and cheaply manufactured, the parts may be restored or repaired when defestive, and it can be manipulated wlthout trouble;

Figure 11 shows the litter for removin the bricks from the can;

Figure 12 is a sectional view showing a series of small cans; and,

Figure 13 is asectional'top and side view 01 the dasher bar.

The numeral 1 represents the frame of the device; 2 the freezer or cabinet; and 8 are openings in the ends of the cabinet for the purpose of permitting the slides 41,

when reciprocated; topass in and out of the same. 7 W

The slides 4 carry the dashers 5 in the operation of the device. 6 are drop covers for closing the openings 3 when the device is used in molding and hardening and the dashers are not in operation. 7 are straps acting as guides for covers 6, and are adapted to be lockedin position by set-screws 8. 9 is a track which is adapted toengage segmental rack 10 when the device is used for molding; and to be disengaged when used for whipping or freezing. 11 are railings on each side of the frame, the same supporting the dashers 5; and 13 are han dles on the ends of the cabinet to operate the freezer. p

14 is a treadle to raise the track and connect the same with the segmental rack when the device is to be used for molding. The wire 15 is connected to the treadle and passes over pulleys 16, the ends of thewire being attached at 17 to the "track to support the same. 18 represents the dasher bar carrying the dashers, said dashers being adjustable on the barto adapt them for cans of different dimensions. 19 are clampsembracingthe dasher-bar and adapted to be locked in the teeth of the same when the screw 20 is operated,

21 are ways in which the slides 1 reciprocate when the dashers are in movement; and 22 are bars having threads wound upon the same to prevent the cream from splashing out or running from the cans. 23 is an arm which connects with the bottom of the cabinet and the dasher at the top and pivoted on bar 27, to operate the dashers; and 2 1 are hangers which support the cabinet when the same is reciprocated, and is disconnected from the segmental rack 9. 25 are screwbolts on each side of the machine, the same passing through the top of the frame 26 and cross-pieces 27, the object of the same being to adjust or regulate the stroke of the dashers. At the base of the cabinet are tubes within which operate rods 61, having cranks 62. The cranks are adapted to engage in eyes 63 at the base of rods 24, and to be locked therein by thumb-nuts 645 when the rods are in operation. In Figure 8 the cranks are shown clamped in the eyes and in dotted lines are shown out of operation. 28 are brackets connected to the top rail 26 of the stand upon which the device is 1 when arm 33 isoperated.

operated, the same forming bearings for rail 11. 29 are short shafts passin through the frame of the device; 30 a Flate connected by bolt 31 to the frame; and 32 is a spring on shaft 29 the purpose of the same being to connect the track and rocker. Arm 33 is for the purpose of throwing the track and rocker out of gear when the cabinet is to'be used for whipping and freezing. 34 is a. forked arm embracing shaft 29, the purpose of the same being to compress the spring and release the track from the rocker 35is a bolt journaled n bracket'36, said bracket being connected to the" frame by "bolts '37. Bolt 35' passes through track 17.

38 is a metallic frame for the purpose of drawing the cans up from the brine, and

has at the upper portion of the same a ratchet- 39 whichis adapted to operate in connection with ratchet 40 on the interior ofthe cabinet; and 41 is an angular ortion of arm 38 for the purpose of operating the same. The dasher bar 18 rests in slides 42 on railings 11., 43 is a lock-plate connected by blocks 44 underneath the cabinet, said plate ispivoted to slides 45 on both sides of the machine, so that when it is desired to lock the rod 23 which'operates the dashers the lock-plate is closed.

In Figure 12 which gives a sectional view of a smaller form of can for the manufacture of ice or block cream, I haveshown catches 46'for the tops of the same. 47 is a lifter for' removing the cream from the cans; and 48 a handlehaving catches 49, which lock inperforations 50 inthe lifter. 51 is the usual form.of can used inthe machine, the same having wings 52 which are adapted to rest in grooves 53 in blocks 54. When the smaller cans are to be used in the eabin et the blocks'54 are reversed, so that v ,to seal the same.

grooves 55 in the opposite side of the same may'receive the straps 56 which rest in said grooves. 57 is a gasketin the flanges 58 Theoperation of the device will be clear from the. foregoing description, the main object being to construct a freezer which can be rocked when it is desired to harden the cream, which is accomplished by means of a segmental rack cooperating with a track; and; when is desired to whip the cream then the segmental rack is disengaged from its track' by means of a catch at each end Hangers support the cabinet to permit the swinging motion of the same.
